Raritan Reverse Polarity Alarm [RPA]

Stay Safe. Know Before You Plug In.

Why You’ll Love It

The Raritan Reverse Polarity Alarm [RPA] is a critical safety device for any boat that plugs into 120V AC shore power. Marina wiring varies widely, and not all outlets are wired correctly. This compact device alerts you immediately when the hot and neutral wires are reversed, which can expose your onboard electrical system—and your crew—to dangerous conditions.

With both visual and audible alerts, the RPA gives boaters a clear warning before serious damage or shock can occur. Whether you're docking at a new marina or returning to a familiar slip, this alarm helps ensure the outlet is wired correctly—before you connect.


Key Features

  • Reverse Polarity Detection
    Instantly alerts you to unsafe dockside wiring with reversed hot and neutral conductors.

  • Audible & Visual Alerts
    Built-in buzzer and warning light make sure you don’t miss critical warnings.

  • Easy Panel Mounting
    Designed to be installed on your boat’s AC electrical panel or near the shore power inlet.

  • Essential Travel Tool
    Especially valuable when visiting unfamiliar marinas with inconsistent wiring.

  • Compact & Reliable
    Simple installation, long-lasting performance, and peace of mind every time you plug in.


Perfect For

  • Cruisers and sailboats that travel between marinas

  • Boats with 120V AC shore power connections

  • Owners adding safety features to older electrical panels

  • RV or marine techs performing electrical upgrades

  • Peace of mind during overnight docking or transient slips
